SPECIFICATION forming part of Letters Patent No. 639.065, dated December 12, 189e.

Application filed February 8, 1897. Serial No. 622,498. (No model.)

-and useful Improvements in Pumps; and I do hereby declare the following to be a full, clear,

and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements ind pumps; and it consists of certain novel constructions, combinations, and arrangements of parts, all of which will be hereinafter more particularly set forth and claimed.

In the accompanying drawings, forming part of this specification, Figure l represents a central vertical section through a pump embodying my invention. Fig. 2 represents a front elevation of the upper portion of a pu m p-v stock. Fig. 3 represents an enlarged detail perspective view of the piston, partly in section; and Fig. 4. represents an enlarged detail perspective vi-ew of one of the couplingcastings. l

A in the drawings represents the pumpstock proper; B, the pump-cylinder; C, the piston, and D D the pipe-sections. The said pump-stock A is mounted in any suitable manner in the platform or covcrof the well or cistern and is provided at its upper end with an upwardly-extending back strip, in which is mounted a handle 61 having an arm a at one end for the attachment to the piston-rod c. A discharge-spout a2 is secured to the front of the pump-stock by suitable bolts eX, which pass through the body of the stock. The said pump-stock is also provided with a pivoted bracket CL3, mounted above the spout and adapted to receive the bail of a bucket to assist in supporting it in position. A shelf or support a4 is mounted below said spout a2 by having its extended sides of mounted in guides a6, which are secured to the opposite sides of said pump-stock. Said arms a5 are adapted to be held in any desired position within the guides a6 by pins ct?, passed through said arms and said guides, respectively. Said support a4 is provided with a discharge-pipe @which extends from the same down through a suitable aperture formed in the top of the cistern, so that all waste water from the support a4 will drain back into the cistern again and not be wasted.

The pump-cylinder B is suitably secured to the lower contracted end of the stock A. The piston O comprises the cylinder c4 and a vertically-movable rod c5, mounted therein and bifurcated at its upper end, as at c2, to permit of the attachment of the piston-rod c. The said cylinder c4 is provided with a suitable packing-ring c','whereby a water-tight joint is formed between the piston and the cylinder. The lower end of said rod c5 is provided with a valve-disk c3, suitably secured thereto and adapted to close the lower end of the cylinder c upon the upward stroke of the piston. The upper end of said rod c5 is provided upon diametrically opposite sides with supports c6, suitably Ysecured thereto and adapted to limit the downward movement of said rod c5. As shown in Fig. 3, the piston occupies the position it takes upon the downstroke to permit the water to rush up through the cylinder c4, so that upon the reverse movement when the valve c3 is ybrought in. contact with the lower end of the cylinder the water above the piston will be discharged from the spout ft2.

The lower end'of the cylinder B is mounted in an annular groove e, formed in the casing E, which latter is provided with a central valve-opening e', covered by an upwardlyopening flap-valve e2. Said casingE is also provided with a recess c for the reception of a wooden block e0, by meansof which the iiapvalve may be screwed in position. This lat ter valve is adapted to open upon the upstroke of the piston to permit the water to pass into the cylinder B, but closes upon a reverse movement of said piston to prevent the water descending again. The saidplate E is also provided with a peripheral liange, s0 located as to catch the drip from the spout as, and thus form a water-joint in said plate E to prevent the escape 0f air therethrough. This plate E is secured to the lower end of said cylinder B by bolts e3, which pass through said plate and through suitable apertured lugs et, mounted upon the cylinder lB. The

said plate E is further provided with a pendent annular flange e5, having a wedge shape, whereby the upper wedge-shaped end d of the pipe-section D maybe firmly jammed therein.

IOC

The said upper section D is supported in position by a brace-rod d', secured thereto by suitable nails or bolts and extending up to the said stock A, to which it is secured in a similar manner, This brace-rod d' passes through apertured lugs b, formed upon the cylinder B, and is adapted to assist in supporting said cylinder by wedges b', which jam in said lugs, and thus secure said rods d iirmly therein.

The pipersections D D are connected together by a casting d2, provided with an internal annular enlargement or groove d3 and flaring ends d4, the latter being adapted for the reception of the respective flaring ends of the pipe-sections. rl`he upper of said flaring ends d4is provided with an annular segmental lian ge d5, forming a Water-chan nel d6, whereby an air-tight joint is formed at this point. The upper flaring end of the section D is adapted to be expanded into the channel cl3 by an aunular wedge CF, forced down within the same. The said pipe-sections D D are further held together by a connecting-rod (Z3, secured to the respective sections by nails or rivers d" and passing through an apertured lug d10, formed upon the connecting casting or joint. The rod is held rmly within this apertured l-ug by a wedge d, whereby all the parts are securedfirmly together. The lower end of the lower section D is provided with suitable apertures dm for the ingress of the water. These apertures are covered by wire screens dll, formed by lacing suitable wires about a plurality of pins (ZM, arranged on opposite sides of said apertures. These screens are adapted to prevent the entrance of any foreign substance into the pipe-sections, and thus prevent them from being drawn upward through the pump.

It will be observed from the foregoing description that the sections of my pump are respectively attached together in such manner as to form, practically, air-tight joints,

which would prevent the perfect action of the pump because of the suction through said pipe sections caused by the cylinder and piston.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. The combination with a pump, of a plurality of pipe-sections, connectors for said sections having annular water-channels formed about their upper ends, and means for discharging the waste Water from the pumpinto said channels so as to keep them always supplied with water and thus form air-tight joints between the pipe-sections, substantially as described.

2. The combination with a pump, of a plurality of pipe-sections having conical ends, a connecting casting having Haring mouth adapted to receive said conical ends, said connecting-casting being provided With an externalange forming a water-channel and with an apertured lug, a rod passing through said apertured lug and having its respective opposite ends secured to the pipe-sections,

-and a wedge adapted to pass through the l GEORGE HARRISON LAUB.
